Specification of Letters Patent.

Application led November 10, 1908. Serial No. 461,929.

To'all fwhom 'it may concern:

Be it known that We, JOHN DEAM KNEED- Lieu and JOHN C. ,MoGARm cit' ens of the United States', residing at Si X- City, in

the county of Woodbury and State of Iowa,

full, clear, and exact descriptionof the' in! ventioii, such as will enable others skilled in the `art to which it appertains to make and use the saine.

Our invention relates to new and useful improvements in roa'd bed equipment and of that class adapted more particularly for constructing .railway tracks, etc., and our object is to provide a combination cross' tie and supporting means therefor, formed of plastic material and metal.

A further object is toI provide a suitable cushioning device, whereby the metallic parts are prevented from destroying the paits'formed of plastic material..

A further object is to provide means inA the plastic parts for receiving and holdingl the spikes en'iployed for securing the rails.

A further object is to provide suitable supporting and bracing nie-ans for holding Athe rails rom spreading.

Other objects and advantages will be hereinafter referred to and more particulai-ly pointed out in the claims.

ln the accompanying drawings which are made apart of this ap lication, 'Figure l is a top plan view of a raginent of a road bed showing our invention applied to use. Fig. 2 is a transverse sectional view illustrating the invention in detail. Fig. 3 is an enlarged sectional view of the securing device. 'Figa l is a perspective view of a length of trackway, showing a slightly modified means for securing the track rails in position. F ig. 5 is a detail view partly in section andA partly in full lines-of one of the* track rails and the supporting and securing means therefor, and, Fig. 6 is an elevation of that form of bracing member shown in Figs. 4 and 5.

Referring to the drawings .in which similar reference numerals designate corresponding parts throughout the several views, l

indicates the supporting sleepers or pots, which are preferably formed of plastic material and arranged inpairs, each pair being secured together and spaced apart by means of a metallic cross tic 2, the ends of the cross tie entering grooves 3 in the sleepers and resting upon cushions 4 placed in the bottom-.of said grooves, said cushions being formedofiany desired yielding material an adapted to receive the jar occasioned by trains passing over, the road-way. The sleepers l are provided with vertical openings 5 in which are adapted to extend metal tubes 6, the lower ends of the tubes being threaded as at 7 to engage burs 8 embedded in the sleepers l, whereby said tubes are securely held in position in the sleepers. rlhe upper ends of the tubes 6 terminate flush with the bottom of the grooves 8 and I are positioned below openings 9 in the cross tie 2, so that the spikes l0' employed for holding the rails l1 against displacement, will-enter said tubes. i

The spreading of the rails is edeetually prevented byv providing brace members 12 along the outer edges lof the rails, said braces having their inner ends arranged to extend over the base of the rail, while the body portions and opposite ends thereof are provided with openings to receive the spikes l0, the openingsin the braces registering with-the openingsin the tie 2.

rThe spikes l0 are securely held in the openings 9 and the heads thereof inrengagement with the rail and securing devices by inserting cores in the tubes 6, said cores being preferably formed of wood so that when the spikes are driven therein, the wood will expand sufticiently to adinitthe spikes, but in vieuv of the snug fit ofthe cores in the tubes, the spikes Will be' rnily gripped by the wood and prevented from casually leaving the vopenings or rising a sufficient distance to loosen the rail.

In view of the fact that the tubes 6 are removably secured in the openings in the sleepers, said tubes may be readily removed and a new core inserted therein and it will further be seen that should the heads become brokenfroni the spike, said spike may.

be driven entirely through the core and a new spike inserted in its place. It will like- -wise be seen that if desired, a cushioning plate 18EL may be introduced between 4the base of the rails ll and the upper face of the tie 2, in which event the force of the jar occasioned by the train, will be entirelv eliminated from the sleepers. u

Tn Figs. 4l, 5 and 6 we have shown a slightly modified form of construction, in

that we have provided a 'chair 14 for the llt) Vle

Til

rails, the base l5 ot which rests in a cavity v16 formed in the upper face ofthe sleeper l, said base having a groove 3a to receive the end of the cross tie 2, said base also having openings 5)@ to receive the spikes l0. At the outer end the base l5 and at each edge thereof, are inwardly and upwardly extending' arms l i', the contour of said arms `being such as to engage the face ot the the base of the chair le to receive the jar coincident to a train passing `fer the rails, the remainder of the construction being similar to the construction disclosed in Figs. l, 2 and 3. v

What We claim is:

l. In a road bed etuiipment, the combination with plastic sleepers having channels and vertically disposed openings therein; of a metallic tie adapted to secure said sleepers in pairs, said tie having openings` therein registering with the openings in the sleepers, rails resting on said sleepers and tie, spikes adapted to hold said rails in position on the sleepers, tubes adapted to enter the openings in the sleepers, means to removably secure the tubes in the openings and additional means carried by the tubes to engage said spikes and hold the same in position.

2. In a road bed equipment, the combination with plastic sleepers having vertical openings therein and grooves in the upper aces thereof; of rails adapted to rest 0n said sleepers, metallic tie connecting said sleepers in pairs, aA chair for each sleeper having brace arms thereon and grooves to receive the tie, spikes adapted to hold the rails and chairs in position on the sleepers and removable means'seated in the vertical openings in the sleepers to engage the lower ends of the spikes and hold the same in engagement with the rails.

3. In a'road bed equipment, the combination with sleepers having vertical openings therein, a tubeadapted to enter each openy ing, a bur embedded 1n the sleeper adapted to engage and hold the tubes and a Wooden core Within the tubes.

4. In a road bed equipment, the combination With track rails; of plastic sleepers to support said rails, said sleepers having cavities, rail chairs adapted to Aenter said eavities and receive Vthe rails, a cushioning plate below said chairs, said chairs' having invardly and upwardly extending arms adapted to engage parts of the rails and means to secure the rails and chairs to the sleepers.

n testimony whereof We have signed our names to.this specification in the presence of two subscribing Witnesses.
